Problems solved by technology

[0003] Downloading data from each collection station sequentially based on the conventional method and saving it to the PC has many shortcomings. For example, the basic process of exporting data from each station in sequence is to establish a connection, search for data, download data and disconnect these basic operating procedures, especially when the data When the amount of file data is large, it will take a lot of time to download the data, which is not conducive to actual operation
Secondly, the collected data is stored in multiple data files, and the data recovery personnel need to have a certain understanding of the storage format, otherwise the wrong data file may be exported, which may cause the operator to fail to download the correct data file if they do not know the data file. data files, there are certain technical requirements for operators
Thirdly, due to some special circumstances, there may be errors or abnormalities in the exported data files. At this time, it is impossible to immediately judge whether it is caused by abnormal sampling at the collection station or data recovery, which will cause inconvenience to later data analysis.
[0004] On the other hand, during the data downloading process, there may be special circumstances where the transmission needs to be disconnected or the data transmission is interrupted due to an abnormality. Effective interaction. In this case, the traditional socket-based resume file transfer technology cannot be used here. As a result, the entire data file will be re-transmitted, increasing the time and resources for retransmission.

Abstract

The invention discloses a method for achieving the data recycling of a no-cable storage-type seismograph, and the method comprises the steps: building a no-cable storage-type seismograph data recycling topological system based on a switcher, taking the no-cable storage-type seismograph connected to a port of the switcher as a collection station mode, enabling a main unit to create a recycling datafile table, transmitting the data file table to all collection station nodes through the switcher, enabling all collection station nodes to analyze the recycling data file table, and then carrying out the parallel retrieval of data files meeting the requirements, and finally enabling the collection station nodes to upload the data files in a parallel manner. In addition, the method employs the multi-thread technology and a breakpoint resume technology for improving the basic function of the data file transmission, thereby improving the recycling efficiency of the data files, and providing more convenient and efficient data recycling services.

Description

technical field [0001] The invention relates to the field of a cable-free storage seismograph, in particular to a data recovery method for a cable-free storage seismograph. Background technique [0002] The cableless storage seismograph is a device that stores real-time collected data in a local collection station. After the construction is completed, the data stored in the collection station is downloaded and recycled, and then the data is synthesized and processed. The data recovery of the cable-free storage seismograph described in this manual is based on the TCP / IP protocol and uses the network port to communicate with common PCs. The conventional cable-free storage seismograph data recovery method is to use network cables to connect each collection station in turn. After the connection is successful, find the data files of interest from the collection stations and download the data files to the local PC host. [0003] Downloading data from each collection station seque...
